You're right. AppImage can be a viable alternative. However, it's
Linux only. And it doesn't integrate as well into package managers
(eg. apt on Debian systems, or pacman on Arch). I currently "natively"
support Windows, Mac, Ubuntu and Arch Linux. Other distributions could
be supported via AppImage.
